Genesis 48:13-16

Then he positioned the boys in front of Jacob. With his right hand he directed Ephraim toward Jacob’s left hand, and with his left hand he put Manasseh at Jacob’s right hand. But Jacob crossed his arms as he reached out to lay his hands on the boys’ heads. He put his right hand on the head of Ephraim, though he was the younger boy, and his left hand on the head of Manasseh, though he was the firstborn. Then he blessed Joseph and said, “May the God before whom my grandfather Abraham and my father, Isaac, walked— the God who has been my shepherd all my life, to this very day, the Angel who has redeemed me from all harm— may he bless these boys. May they preserve my name and the names of Abraham and Isaac. And may their descendants multiply greatly throughout the earth.”
